Could see a few strong to severe thunderstorms this weekend:
Area Forecast Discussion
National Weather Service New Orleans LA
345 AM CDT Fri Jul 7 2017
.SHORT TERM...
A weak cold front is expected to migrate south towards the I-20
corridor Saturday night, and possibly into southern Mississippi,
near the northwest border of the forecast area Sunday.
Precipitable water values will remain around 2 inches, and are
likely to remain high into the weekend, although a wedge of
slightly drier air may move south with the frontal boundary into
far northern areas Saturday into Sunday. Regardless, the rain
chances are expected to remain on the high side during daytime
hours, and even a bit elevated at night in eastern coastal areas
Friday night and most of the area Saturday night and Sunday night
with weak northwest to north flow aloft developing.
Strong to severe thunderstorm potential will have to be monitored
going into the weekend. Today should only see some stronger
storms with frequent lightning, torrential downpours capable of
producing minor flooding, and wind gusts up to 40 mph. Saturday
will introduce some drier air in the mid levels along with fairly
steep mid level lapse rates and continued high theta-e in the
lower levels. For these reasons a marginal Risk of severe
thunderstorms has been extended to encompass an area along the
interstate 10/12 corridor northward for Saturday. The main
threats should be isolated damaging wind gusts and hail.
Temperatures will be dependent on where more persistent/numerous
showers and associated clouds develop, but overall should be near
to slightly below seasonal averages for highs.
.LONG TERM...
The western mid/upper high/ridge is expected to slowly move/
develop eastward into the central U.S. with the eastern U.S.
trough de-amplifying and moving northeast Tuesday into Wednesday.
The north Gulf coast will remain in a moist regime with the
stronger ridging aloft remaining well north of the region, however
a gradual lowering of rain chances and a gradual minor rise in
temperature should occur going into Wednesday and Thursday.
